Even if I use this configuration
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.0.2-SNAPSHOT</version>
<goals>
<goal>exploded</goal>
</goals>
</plugin>
or
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.0.2-SNAPSHOT</version>
<executions>
<execution>
<goals>
<goal>exploded</goal>

mvn package
